Well, I didn't so much as cry, I don't cry much, but going by most emotional anime series, I'd easily say Fairy Tail. The series does things that I don't think most shounen series are supposed to, they make you feel sorry for the villains for one. There are also really heartwarming and kinda tearjerking moments all over the place. Basically all I can say is Hiro Mashima made my emotions his bitch.

Then there's one single moment in One Piece that's extremely sad and hard to watch and it's not even a person's death(though there is one that's just as sad involving a person's death). And if you've seen the anime, you know exactly what moment I'm talking about.

"I hate this town. It’s too filled with memories I’d rather forget. I go to school every day, hang out with my friends, and then go home. There’s no place I’d rather not go ever again. I wonder if anything will ever change? Will that day ever come?"-Okazaki Tomoya

Kaichou wa maid sama made me cry because it ended, not because sadness in the plot :(

I really wanna watch Code Geass, but I always get distracted by other anime >.<
